Intermolecular Forces and Their Types

What are intermolecular forces?

• Forces that only exist in ionic compounds

• Forces that repel molecules from each other

• Forces that attract neighboring molecules

• Forces that hold atoms together in a molecule

Which of the following is a type of intermolecular force?

• Permanent dipole-dipole forces

• Covalent bonds

• Ionic bonds

• Metallic bonds

What makes hydrogen bonds stronger than regular dipole-dipole forces?

• They occur in all molecules

• They are the same as covalent bonds

• They only occur in metals

• They involve hydrogen and a highly electronegative atom

What are van der Waals' forces?

• Permanent dipole-dipole interactions

• Induced dipole-dipole interactions

• Forces that are stronger than covalent bonds

• Forces that only exist in polar molecules

Why do van der Waals' forces increase with more electrons?

• Because more electrons mean more covalent bonds

• Because more electrons create stronger ionic bonds

• Because more electrons lead to stronger induced dipoles

• Because more electrons make molecules heavier
